According to Bill Steele, Director of Information Services with the
University of Washington seismology lab, there are no signs of volcanic
activity, but the quakes could represent changes in the stress field at
the volcano.

The larger earthquake "was pretty
shallow," said Steele, "a depth of about five kilometers."

The aftershocks have been relatively
large, said Steele. "At least two greater than magnitude 2.0, perhaps more, and
then a lot of little ones."
